"Bring the most unusual prop you can find ... something weird, something that people might not know what it is, and something so big that everyone in the balcony will be able to see it," Mochrie and Sherwood say in the release. "Don't let us down. The funnier the prop, the less work we have to do."

Props must be able to fit through a 3-inch-by-3-inch opening. Some of the props will be used during the performance. Items should be dropped off in the lobby upon arrival to the theater and will be returned after the show.

Mochrie and Sherwood are best known for their frequent appearances on the American version of the television series "Whose Line Is It, Anyway?" The show originally ran on ABC and ABC Family from 1998 to 2007 and was hosted by comedian Drew Carey. It was revived in 2013 on The CW Network, with host Aisha Tyler.
